On your way to the Suwon Station Underground Shopping Center, you passed a playground; it seems to be empty right now.

You used to spend my free time here with Yeji.

Yeji is four years younger than you and is your mother's daughter and also our neighbor, as Yeji's mother and your mother have been so close since high school that they decided to live next door to each other. Yeji's older brother, Sunghoon, was a and is talented figure skater, but he gave up figure skating early, just like you, to become a K-pop idol, except You're not one.

He's now a member of a world-famous band called Enhypen. Enhypen is a seven-member boy group.

Sunghoon is a year older than you, and we've been best friends since you were little, probably because we live next door to each other and our mothers are close. But since you moved to Germany with my father after my parent's divorce, you've been friends for a long time. In those six years, you barely had contact with Sunghoon. There was never anything more than friendship between him and me. Especially since you were eight time zones apart, and his number is no longer available; he probably changed his number when he became an idol

It was because of him that you started figure skating early on. You thought it was cool and you enjoyed it.

You wonder if he's forgotten you long ago?
